Appncation meav october 2s, 192s. 'serial No. 144,874.

Myinvention relates to-oil burners, that is to say, to a device adaptedfor the burning of fuel oil to utilize the heat of combustion thereof inboilers .and heaters'of various' provide an oil burner in which the fueloil will be so broken up that all parts thereof will be exposed to theair,'whereby the combustion will be. complete and greater efficiencywill result.

provide a device of the character aforesaid which is so constructed andarrangedas-to l yutilize thepassing current of air for the actuationthereof.

The nature and characteristic stgod from the following description,taken in connection with the accompanying drawl ings forming parthereof, in which:

Figure 1 is a vertical central sectional view of an oil burner embodyingthe main features of my present invention;v

Fig. 2 is a top or plan view thereof;

. Fig. 3 is a horizontal section taken'apvproxiinately on the line 3-3of Fig. 1;

Fig. 4 is a section, to a certain extent dia- 25 features of grammatic,'illustrating the arrangement with respect to each other of the bladesof a stator and rotor, constituting portions of the Fig. 5 is anenlarged fragmentary section illustrating th construction andarrangement of rings E.for successively breaking up the oil into aprogressively increasing numberv of parts.

A further object of my invention'is toinvention will be more readilyunder-y plained.

Referringto the drawings, in the particu` lthe upper end of the standard12, a

ball bearing 15 being provided at the bottomy of the sleeve 14 wherebysaid sleeve 14 the parts carried thereby may freely rotat'.

The upper end of the sleeve v14 is provided Witha flaring cup shapedextensionflf Secured to theoutcr surfaceof theeup kshaped extensionl 1.6of the `sleeve 14. is anannulus 17,'having a shoulder port-ion, 18 for apurpose to be presently explained. ifThe annulus 17 carrles a pluralityof rotor-,bl-'ades 19, the outer ends of which are securedlfin a ring20. A plurality ofxradially disposed stator vblades 22 are arrangedimmediately below the rotor 'blades 19, said stator blades beingsupported by an outer ring 23 and an inner ring-24;. The outerring23jisixedly positioned to the interior of the vhousing 10, preferably bymeans of any annular shoulder 25 provided onv the inner surface ofthewall of thehousing. A frusto-conical deflector 26 is carried by thestandard 12,l and serves to deflect the air throughfthe stator blades-22 for a purpose t6 be presently explained.

Upon the shoulderportion 18 oftheannulus 17 there is mounted the innerring portion. 27 of a spider frame 28,the arms29 of which carry aplurality of vertically arranged supporting pins' 30. Thepins 30 serveas a means for supporting a plurality of oil dividing rings'which areconcentrical-v ly arranged with respect to each other in a progressivelyincreasing numberin each series, as will be hereinafter more fully eX-The innermostl oil dividing ring 31 has its inner portion notched orserrated as at l3.2, thereby to provide aL plurality of channelsextending alternately to the. topI and bottom surfaces of the ring 31;:It-should be noted that the medial line of the serrated inner portionof the ring 31 lies in the plane 'of the rim of the cup .shapedextension 16 of the sleeve 1li.-

Concentrically arranged on the outside of f' the ring 31 are two rings33, .each of whichy is provided, in a manner similar tov that of thering 31, with a plurality of notches or` serrations 34 extendingalternately. to the i105 top and bottomfsurfaces ofeach ring 33. j

The medial line .of the serrated inner por.

tion of each rin 33 lies in'the plane of one of the periphera edgesofthe inner ring 31.

Concentrically arranged on the outside of the rings33 are four rings 35,each of which is providedin a manner similar to that of the rings 33,with a plurality of notches or serrations 36, extending alternately tothe' top and bottom surfaces of each ring 35. Here again the arrangementis such that the medial line of the serrated inner portion of each ring35 is arranged in one of the horizontal planes of the peripheral edge ofone of the rings 33.

It will, of course, be understood that still other series of rings maybe concentrically arranged on the outside of the series of rings 35, ifit be found that lfurther subdivision of the fuel oil will be required.This may be necessary in burners of large capacity.

The operation of the device may now be explained. Air under pressure issupplied i 'by means of a blower or other suitable ap- -paratus to theinterior of the housing 10 f through the conduit of which the'extension'-20 11 ofthe housing 10 forms a part.- The passing current of air willbe' guided ,by means of 'the frusto-conical member` 26, so that the samewill pass through the stator blades 22 and thereby be deflected againstthe rotorblades 19 which are carried by/the annulus 17. 4In this manner,a rotary move-' ment of high speed will be imparted to the y sleeve 14and the parts carried thereby/ `The fuel oil being supplied by means ofthe piping 13 to the vertical 'standard 12, will pass up through thesame into the cuplike extension 16 of therotatable sleeve 14. As thecup-like extension 16.is rotated at a high rate of speed, in the mannerhereinbefore set forth, the fuel oil, due to the centrifugalaction,'will be carried upward over the haring inner surface of thecup-like eX- tensionl, until itreaches. the rim thereof, whence it willbe thrown 0H in a relatively thin sheet, and will impinge against theserrated inner portion of the ring 31.

As the oil impinges against the serrated inner portion of the ring 31,the same will be broken up into a plurality of subdivisions, one-half ofwhich will pass to thetop surface of the ring 31, and the other half ofwhich will pass to the bottom surface of the ring 31, by reason of thepeculiar arrangement of the notches or serrations provided in the innerportion of the ring 31, as hereinbefore described.` The oil which passesover the top and bottom surfaces of the ring 31 will in turn be thrown'ofrom the periphery thereof, whence the saine will impinge against theserrated inner portions of the rings 33.

In like manner, the oil will be thrown off from the upper and lowersurfaces of each of said rings'33 by centrifugal action, and willimpinge against the serrated portions of the'rings 35, where the samewill be still further subdivided. If but three series of rings areprovided, as shown in the drawings, the oil will be thrown off from theperiphery of the upper and lower surfaces of each of the rings 35, andwill be in such condition that all parts thereof will be accessible tothe air, thus insuring the efficient and.. l

complete combustion of the oil.

It will be seen that there is thus provided a simple and eliicient formof oil burner which will break up the oil so that all parts theigeof maybe readily consumed, and which is adapted to be actuated by the passingcurrent of air, thus eliminatingthe necessity of I claim as new anddesire to .secure'by Let` ters Patent, is z 1.
